Welcome to Test + Build!

What is Test + Build?

Test + Build helps you run trials, with personalised feedback and support from our highly-skilled team.

Test + Build provides users with materials to design their own behaviourally-informed communications and supports them in testing the effectiveness of these designs with a randomised controlled trial (RCT).

This website holds a wealth of information developed by The Behavioural Insights Team (or B I T). On here you will find guidelines, methodologies and other materials to help you through the process of running your trial.

At certain points in the process a researcher from B I T (who you’ll have been matched with at the beginning of your project) will be brought in to support you with some of the more technical aspects of your trial. We’ll go through these elements in more detail shortly. ​Results from one of our previous trials can be found here.

The Test + Build platform was so easy to use and so informative. It helped us clearly define our project objective and design the interventions. Additionally, the Test + Build team provided excellent support, sage advice and carried out the complex analysis giving us confidence that the excellent results were real and not just a mere coincidence."​Patrick Knight, Finance Operations Systems Manager at Medway Council
